聚茀 (polyfluorenes)及其衍生物之固態薄膜對於光電應用而言，具有良好化學性質、熱穩定性及高螢光效率。然而，因聚茀分子在經過高溫熱處理後或者是在薄膜態中，容易產生高分子鏈之分子間作用，結果發生群聚(激發雙體、凝聚體)。此研究中，利用植入之聚茀分子交替以及團鏈共聚物於交聯網狀結構基材中，來限制其群聚之延伸。
首先，將二種平面芳香族發光體單體(例如：蔥(anthracene)、茀(fluorene)以及砒啶 (pyridine))以Suzuki偶合法(coupling)做成交替共聚物(alternative copolymer)，此交替共聚物由於相鄰二苯環鄰位(ortho-)氫原子之空間障礙形成扭曲(twisting)之分子鍵形態，此扭曲分子鏈使得高分子鏈不易相互靠近，從而降低其群聚之形成。進一步地，上述之交替共聚物亦可以使用原子轉移自由基聚合法(atom transfer radical polymerization)進一步與聚甲基丙烯酸甲酯(poly(methyl methacrylate))化學連結而得到一柔軟–剛硬–柔軟(flexible-rigid-flexible之三團聯共聚物(triblock copolymer)，此三團聯共聚物中間為一扭曲高分子鏈，二邊為具阻隔作用之柔軟高分子鏈，可有效地降低群聚趨勢。在高分子薄膜經過高溫熱處理之後，結果指出此系列高分子具有穩定性藍光，有此得知其熱穩定性和群聚效應兩者乃會受到高分子化學結構之影響。確實地，含有蔥之共聚物擁有較大之立體障礙而使得空間上扭曲之分子鍵形態，故具有較少群聚效應。對於聚茀高分子而言，此策略可以有效地改善之，並且使得此高分子可以被廣泛地應用。第三，將上述之高分子溶解於壓克力衍生單體中(methyl methacrylate (MMA)/ di-trimethylolproane tetracrylate (DTTPT)以及光起始劑，並配置所需之溶液。將配製之高分子混和液施予紫外光光硬化反應而產生固態薄膜複合材料交聯網狀物中含有螢光高分子。可利用此非流動性網狀交聯體將成功地凍結住螢光高分子構形與高分子群聚程度。
對於光硬化之前後系統而言，凝聚體之程度並可利用吸收、螢光、螢光激發光譜儀器觀察而所得知。研究中在討論對於控制凝聚體之程度，發現其重要之因素為高分子濃度。高分子材料經高溫熱處理之後，硬化複合材料相較於聚茀衍生物高分子，複合材料更具原有高分子構型及熱穩定性。並且可有效地限制群聚效應出現。在大部分研究中，量子效率可被用來測量並鑑定策略之影響。

Polyfluorene (PF) and its derivates as well-known fluorescent materials are promising materials in optoelectronic applications due to their high quantum yields in the solid state. Nevertheless, the easy chain inter-action in PFs to result in the unfavorable associations (aggregate and excimer) are generally considered to be detrimental to the emission efficiency in the concentrated solid state and/or at high temperatures. In the study, restraining the extent of associations is therefore by embedding fluorene-based alternative and block copolymers in crosslinked network as matrix.
Firstly, alternative copolymers with fluorene connected by anthracene (or pyridine or fluorene) ring were prepared through Suzuki coupling. In this way, the steric hindrance between the o-hydrogens in the neighboring aromatic ring causes the twisting of the constructed polymer chain and the resulting twisting chain conformation keeps the polymer chains from the unfavorable inter-chain interactions and reduces the extent of the association. Secondly, the alternative fluorene-anthracene copolymer (a-PFA) from the first approach can be further chemically formulated to obtain a triblock copolymer with the central a-PFA rod block connected by two flexible poly(methyl methacrylate) (PMMA) segments. In this way, the two flexible PMMA chains serve as spatial isolator to keep the central PFA rod from approaching each other and a reduced extent of association is expected for this block polymer of b-PMMA-PFA. Thirdly, all the alternative and block copolymers cited above were immersed in the curable liquid methyl metharcylate (MMA)/ditrimethylolproanetetracrylate (DTTPT) monomer mixtures and photo-irradiated to obtain composites with the fluorescent polymers immersed in the cured crosslinked network. The chain morphology and thus the degree of associations will be successfully frozen by the immobilized crosslinked network.
For systems before and after photo-irradiation, the degree of aggregation was evaluated by Uv-vis absorption, photoluminescent (PL) and PL excitation spectroscopy. Polymer concentration was found to be important factor in controlling the degree of aggregation and was discussed in this study. In addition, the cured solid composites after high-temperature annealing were studied and compared with pure PFs to evaluate the effectiveness of this crosslinking strategy in restraining the extent of aggregation. In most cases, quantum yields (ΦPLs) also were measured to evaluate the effectiveness of this strategy.
